Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of dismay when you notice something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is constantly kicking in and shutting off. However, before you panic, there are a few things you can check when you realize your furnace seems to be shutting off more than usual than it should be.

  1. Check the air filter in your furnace—You may think that air filters are only used to help keep the air inside your home cleaner, but the filters also help keep your system clean. Your first step when you recognize an issue with your system should be examining your air filter to see if it should be replaced. If it’s clogged or dirty, it can make it tough for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats months ago and forgot about it, even more so when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is going on or if it might need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your space, such as in direct sunlight or by another heat source, it could be mistakenly assuming your home has met the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have appropriate insulation, your furnace is likely to shut off more regularly. Walk around your home and check the windows to ensure they are all closed and inspect the seals around your windows for any drafts or cold air coming into the house.

While you can look at these issues by yourself, if issues still occur after these checks, it might be time to call in the experts. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could cause more costly repairs or even a replacement.
